The Forgefix Lightning Bolt is a totally removable, rotation setting, medium to heavy-duty, thread forming anchor. It is ideal for either temporary or permanent anchoring into base materials including brick, concrete, hollow brick or block work. The Lightning Bolt is particularly well suited for close to edge or fixing, as it does not expand or burst the surrounding base material. It is through fixing, eliminating the need for marking & re-positioning. To use, simply drill through fixture & into the base & simply screw & tighten. The bolts are Zinc Yellow Passivated for increased resistance to corrosion & have Hex Flange heads. The Flange acts as a fixed washer distributing the load under the bolt head. The Hex head offers optimum torque when used with spanners or sockets. APPLICATION Widely used for fixing batons, balustrades, handrails, racking & holding down machinery, plus many more installation applications.

It provides a coating that is aesthetically pleasing, & which offers excellent resistance to corrosion. Lightning Bolt Hexagon Flange Head M6 x 50 Box 100
